To ail whom it may concern:

Be it known that I, DANIEL H." MAHONEY, a citizen of the United States, residing at Vincenn'es, in the county of Knox and State of Indiana, have invented certain new and useful Improvements in Excavating and Loading Machines; and I do declare the following to be a full, clear, and exact description of the invention, such aswillenable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures 'of' reference marked thereon, which form apart of this specification. M

This invention relates to an improved machine designed more especially for use in connection with railroad-construction trains for the excavation and transportation of earth along the line of road; and theinvention has for its object the production of a simple and durable appliance by the operation of which the construction of railroads and other works is greatly facilitated and is-accomplished in an economic manner.

The nature of theinvention will be readily comprehended, reference being had to the following detailed description and to the accompanying drawings, in which- T Figure 1 is a perspective view of an excavating and loading machine embodying the invention, the machine being shown movably' supported on atrain o1"; railway flat-cars.

Fig. 2 is a side elevationof the same, show-' ing the scoop in elevated position to unload.'

Fig. 3 is a front elevation of the machine, showing the adjustment for deep cuts. Fig. 1 is an enlarged perspective view of the scoop.

Figs. 5 and 6 are detail views showing the ad justable connection between the scoop and boom. Fig. 7 is a detail view showing the means for supporting the lower end of the boom-guide and the brace for the guide extension.' Fig. 8 is a detail view of the upper end of the beam-support, showing the shiftable beam-hook." Fig"; 9'is a detail view of one of the devices forclamping the machineframe to the car.

Referring to the drawings by numerals, 1 denotes a carrier-frame comprised of side members 2 2 and end members 3 3, which members are firmly bolted or otherwise secured together and are braced by cross-pieces V ,4 4. The ends of theside members are rounded or beveled at their outer and lower sides and the end members are above the plane of the side members, whereby the latter form the support for the frame and parts carried thereby. Erected from the corners of the frame are fourrposts, two of which, 55, are connect ;ed at their upper ends by a cross-bar 6, and the other two, 7 7, are inclined inwardly and secured directly together. The posts are braced by inclinedpieces 8 8.

9 is a beam, preferably of truss form,"secured at its lower end by'a swivel connection intermediately of the'cross-barG. Between its ends the beam is supported onthe posts 7 through the medium of ahook 10, which is shit table, whereby the beam may be supported at either side of the post' ends, asindicated in Fig. 8. Atits upper; or outer end the beam is provided with a pulley-block 11 and an eye or pulley-block12, the purpose of which will be presently stated.

13 denotes'aboom, theinner end of which is swiveled to the cross-bar 6. Said end is preferably widened and is pivotally secured by a bolt 14 to a roller 15, rotatably mounted at its ends in bearings16 16. The boom end has at its under side a wear-plate which contacts with the surface of the roller and prevents the boom from" turning; but through the described connection the boom is permit- .ted both a vertical and a horizontal movement, and hence may be raised and lowered inianinc lined plane. Attached to the outer jendfof the boom is a cable 17, which is passed around the pulley l1, and thence around a pulley'18 on the frame, and finally is secured "to the drum of ahoisting-engine. (Not shown.) 'The cablepreferably passes over a roller 19 at the opposite end of the carrier-frame.

guide or fender 20, consisting, preferably, of two bars secured at intervals in separated relation by bolts 2l or' the like, The guide is adj ustably connected'toward its upper end to the top of the post 7 by means of a bolt 22, which is passed through the post and through one of a series of holes 23 in the guide. Toward its lower end the guide is supported away from the post by a brace 24, consisting of two connected bars having notches at their Secured to one of the posts 7' is an inclined;

ends to engage one of the bolts 21 of the guide and having toward their inner ends a series of holes 25, through which and the post is passed a bolt 26. The boom is directed in its movements by the guide, with which it is in sliding contact, and to reduce friction and lessen wear a roller 27 is interposed between the guide and boom, the roller being carried by the latter.

The boom carries at its outer or free end a scoop 28 of rectangular form, but having its lower portion preferably conforming to the shape of the ditch or other excavation to be made. The scoop is open at its front end, and its rear end is normally closed by a dumping-door 29, which is hinged at its upper edge to the scoop'body and has a self-locking catch 30, moved by hand either directly or through a cord to release the door and permit the discharge of the load. The bottom of the scoop is extended at its front edge 31 and sharpened to enter the ground, and in connection with said front edge are a number of plow-points 32. The scoop has at its front a bail 33,which is pivoted by a bolt 34 to a block 35, secured to the under side of the outer end of the boom. In the lowered position of the boom the scoop is at one side of the carrier, and the distance of the line of traverse of the scoop from the carrier being variable, through the adjustment of the brace 24, to make the cut whereverdesired the connection between the boom and scoop is made adjustable to bring the scoop into parallelism with such traverse despite the variation in thethrow of the boom. To this end the block 35 is pivoted at one end bya bolt 36 to the boom, and at its other end are holes 37, through any one of which and the boom is passed an adjusting-bolt 38, whereby the scoop may be secured at the proper angle to the boom to bring the lowered scoop into exact parallelism with its line of traverse. To prevent the scoop during excavating from tilting, there is provided on the boom an arm 39, which engages an adjustable stop or shoulder 40 on the top of the scoop. The stop 40 is provided with a series of holes, through which and the scoop-top is passed a bolt 41 to effect the adjustment, and for the purpose of bringing the arm 39 into proper engagement with the stop despite variation in the angle between the scoop and boom the arm is pivoted on a bolt 42, which is tightened when the arm is moved to its proper position. A cord or cable 43 is secured at one end to the rear end of the scoop and is passed through the eye 12 on the beam and then fastened to permit of adjustment, preferably, on the cross-bar 6.

Although the machine is capable of utilization in excavations generally, it is designed more especially, as before stated, for use in railroadbuilding, and in the drawings the machine is shown as supported upon and movable along a train composed of flat-cars 44 44. The side frame members of the carrier serve as runners, whereby the machine may be drawn over the cars, being guided by the stakes 45 45. In the preferred practice a hoisting-engine is carried by a car at the rear of the locomotive, and to the drum of the engine is secured the cable 17. The machine is first placed on the rear car and sulficiently forward thereof to enable the contents of the scoop to be dumped on the car. The boom being lowered to carry the scoop into excavating position, as shown in Fig. 1, the train is drawn by the locomotive -to move the scoop, and when the latter is filled the train is stopped and the engine is then operated to raise the boom and scoop. In the upward movement the boom is guided by the inclined guide to bring the scoop directly over the longitudinal center of the car, and as in such movement the scoop is partly inverted the contents thereof are entirely discharged upon the opening of the scoop-door. In the return movement the scoop is carried to its lowered or excavating position beside the railroad-track and is righted by the cord or cable 43. As the car fills the machine is moved to a new position on the train by being drawn thereover, this being done, preferably, by the engine, a cable eye or book 46 being provided on the front end of the carrierframe for this purpose. After the entire number of cars have been loaded with earth the train is moved to the point where the filling is to be made and the unloading is then accomplished by the usual power-ploworin anyother desirable way. During the operation of excavating the machine is secured in position on the car, preferably by the use of the clamps 47 47, which are placed at the side opposite that occupied by the boom and scoop. These clamps preventlongitudinal movement of the machine and also tilting, which might otherwise occur when the scoop is loaded. The beam, the guide, and the boom may be shifted to the opposite side should occasion demand, and, if desired, the entire machine may be reversed in position, in which event the movement of the train must also be reversed.

Attached to the lower end of the guide is an extension 48, similar in construction to the guide and adapted for use in making deep excavations. The lower end of the guide or the extension, as preferred, is provided with a series of holes 49, and 50 is a belt which is passed therethrough and which serves to secure the extension adj ustably to the guide. The lower end of the extension is supported by'a brace 51, having sockets at one end to engage a bolt on the extension,and at the other end the bars of the brace are bent outwardly and are notched to engage one of the car-timbers. The extension when not in use is folded against the guide, as shown.
